To aZZ wiom t may concern: i

Be it known that 1, ADAM A. LONG, of Rochester, in the county of Monroeand State of New York, have invented certain new and useful improvementsin Cleaning- Machines; and l do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe reference-numerals marked thereon.

The present invention lrelates to cleaning machines and it has for anobject to provide a construction having' a substantially portable brushor other agitator with suction producing means so located that theoperative will notfbe required to support the same during the cleaningoperation. n Another object of the invention is to provide aconstruction in whichthe driving of the brush or agitator will ceasewhen the latter is moved to a certain position. To these and other endsthe invention consists in certain improvements and combinations of partsall as will be hereinafter more fully described, the novel featuresbeing pointed out in the claims at the end of the specification.-

ranged on a support or table 1 and acted upon by an agitator 2 which inthis instance is in the form of a rotary brush partially inclosed by acasing 3, the brush being preferably carried by a shaft -l journaled inthecasing walls and extended at one end beyond one of said walls to turnin bearings 5 and 5a arranged within a tubular member 6.

The latter is secured to and held in spaced relation to the casing 3 bybrackets7 that are bolted at 8 to said casing, the axial movement of theshaft 4 in the tubular member being prevented by securing a disk 9thereto at one end so as to cooperate with the outer face of the bearing5a. rll`his disk is preferably engaged v:by a screw plug 10 introducedinto the end of the tubular member 6 and preferably carrying an oil cup11 which feeds oil to the disk for the lubrication of the bearing 5a,the bearing 5 being lubricated by a cup 12.. The tubular member 6preferably serves as a handle for the control of the brush or agitatorand may be inoased by a rubber sleeve 13 and a removable rubber cap 14e,both of which facilitate the manipulation of the machine and at the sametime prevent oil passing from the end of the tubular member.

rFhe driving of the brush or agitator 2 and the suspension thereof ispreferably eected byV an endless cable 15 which passes about a pulley 16rigidly secured to the shaft 4lbetween the casing 3 and the tubularmember 6. 'llhe cable 15 has its two strands leading upwardly from thepulley 16 about a pair of pulleys 17 arranged side by side and mountedon frames 18 which are pivoted on parallel aXesiat 19 to swing laterallywith relation to the cable so that the brush may be carried towardeither end of the table without shifting the cable from the pulleys.From the pulleys 17 the two strands of the cable pass rearwardly to apair of pulleys 2() and thence downwardly about a pulley 21. Preferablythe pulley 21 is supported on an upright frame coniprising two rods 22secured at the rear of the work support l and having at theirupstoppage,

v counterbalance the brush and the pai ts carried thereby there isemployed a weight 24,

or other suitable device, which preferably carries a pair of rollers 25.coperating wlth both strands of the cable 15 between the pairs ofpulleys 17 and 20. rihis weight is guided vertically on guiderods 26depending from the arm 23 and having a stop 27 at their lower endsweight and sustain the latter when the brush is moved upwardly to acertain position. Of course, when the weight reaches this stop alltension will be removedfrom the cable 15 and driving connection betweenthe pulley 21 and the brush 2 will be broken.

The cable, unless otherwise affected, will not stop immediately butwilly continue to move under its own momentum and with the end in viewof effecting an immediate there are employed brakes 28, in this instancein the form of levers pivoted to the weight 24 at 28a and havingfriction faces 28b to coperate with sides of the pulleys 25 and stoprotation of the latter, thus imposing friction on the cable 15. rl`helevers in this instance depend below the weight 24 so that they mayengage the stop.

27 to beshifted into cooperation with the pulleys 25 when `the weightmoves to said stop. Springs 28C act on the levers to hold them out ofcontactuwith the pulleys and against the stops 28d.

The brush may be supported in its inoperative position upon a devicecomprising two .spring arms 29 clamped to one of the rods 22 and havingtheir forward ends converging at 30 to facilitate their introductionthrough a loop 31 formed on the casing 3 inclosing the brush. Anadjustable stop 29a may be arranged on the arms to limit the movement ofthe casing on the arms 29.

While the brush is supported in inoperative position the cable 15, ofcourse, is slack and consequently it is desirable to provide some meansto prevent the cable leaving the pulley 16. This is accomplished in thisinstance by a pair of pulleys 33 coperating with the outer sides of thetwo strands of the cable and preferably carried'upon a movable orswinging member 34 which is journaled on the tubular portion 6 to turnabout an axis coincident with `the axis of shaft 4, thus permitting thebrush to be carried to either end of the table without imposing anystrain on the cable. To prevent the swing member moving too freely,

a friction member 35 in the form of a plate guided on headed studs 36 ispressed toward' with a passageway to cooperate with the l the swingingmember by helical springs 37 surrounding said studs, stops 38 projectinginto the path of the swinging member at the limits of the movement ofthe latter. rThe swinging member 34 may also carry a pin 39 which liesbetween the two strands of the cable and prevents the latter fromleaving the pulleys 33.

For the purpose of removing the dustv agitated by the brush 2, thecasing 3 surrounding the brush is preferably provided 48 having anintake arranged at its bottom and to one side of the brush. The outerwall 48a of the passageway depends lower than the inner wall 48b so thatthe dust may enter lfreely into the pasageway but will be prevented frombeing carried beneath the casing. In order that, all possibility ofthelatter action will be obviated, the wall 48a carries a dependingflexible strip 48d which provides a tight joint between the materialbeing cleaned and the casing for any operating position of the machine.It 'is also desirable to control the size of the intake opening and tothis end a piece of pliable sheet material secured to the inner wall 48bof the passageway and is extended upwardly therein. By moving the end48C of the sheet material the opening may be varied in size to meet thecondition under which the machine is operating.

' To the end of producing suction in the passageway 48, a flexible dustconductor or tubing 47 connects with the casing and leads to astationarily-supported suction-producing means, such for instance as afan 4() which may be supported on upright rods 22. The tubing 47 may besupported in any moved to either end of the work support withouttwisting the tubing. The swinging movement of the elbow is limited bystops 47 b lying on opposite sides of the elbow and carried by a splitclamp or collar surrounding the reduced end of the member 41. The

latter has an enlarged chamber 42 and is preferably secured to the fancasing by headed pins'43 on the casing and curved locking slots 44 onthe member, a rotation of the latter effecting a locking or unlocking'ofthe parts and a spring pressedbolt 45 on the member coperating'with thefan casing to hold the member against movement on the fan casing. Theenlarged chamber 42 is pro.- vided to preventv large materials enteringthe fan casing and in order to cause said materials to collect in thechamber, a cone 13( natale? shaped screen 46 is preferably secured tothe fan casing. rlhis screen is self cleaning as its apex is in linewith the direction of the air current leading to the fan, thus causingthe air to move all lint or the like to the base of the cone s o thatthe latter is always cleared.

From the fan casing the dust is carried to a pipe 50 which through aunion 51 connects with the threaded nipple 52 secured to the top 53 of adust container 54 'which has its side walls perforated to permit theescape of air. rlhe top is provided with an annular groove 55 which issecured to the outer edge of a bag 56 of textile material depending intothe container54 to collect the dirt.

The fan shaft 57 has a pulley thereon Connected by an endless cable 58with the pulley 59a on the shaft 5,9 which also carries the pulley 21.On the shaft 59 there is also arranged a pulley 60 to which an endlesscable 61 connects, the latter in this instance being driven by a motor62 arranged on the table 1.

Assuming the motor 62 to be running and that the brush is supported uponthe arms 29, the operator having placed the goods to be cleaned upon thetable grasps the handle of the brush and removes the latter from thesupport 29. As soon as the brush is moved to a position to elevate theweight 24 from stop 27 the cable l5 begins to ymove, thus rotating thebrush. Upon the engagement of the cloth bythe brush, any dust in thecloth will be carried to the intakeof the passage 48 and by the fandrawn through the tube 47 and discharged into the bag 56 which willpermit the'gescape of air but will retain the dust particles. `its soonas the brushing operation has been completed the brush is placed uponthe arms 29 thus lowering the weight 24 to the stop 27 and causing thelatter to shift the brakes 28 into engagement with the pulleys 25 whichwill eect the stoppage of the cable 15. When the bag 56 is filled withdust the coupling union 51 is manipulated todisconnect the top 53 fromthe pipe 50 so that the bag 56 may be removed from the chamber 54.
